The top three -- No.1 Alabama, No. 2 Clemson and No. 3 Notre Dame -- continue to sit comfortably in the top four, though the Fighting Irish moved up one spot in this week's rankings, which were released Tuesday night.

The Wolverines resoundingly defeated Big Ten rival No. 20 Penn State last week to move from No. 5 to No. 4. LSU stumbled from No. 3 to No. 7 after being shut out at home against the dominant Crimson Tide.

"Their defense is extremely strong,'' selection committee chairman Rob Mullens said of LSU still being ranked No. 7 despite having two losses. "Their two losses come against No. 1 Alabama, on the road to Florida.''

According to ESPN's Football Power Index, there is just a 9 percent chance that the top four teams in the CFP rankings will all win out.

Georgia continues to wait patiently just outside the top four, having moved up from No. 6 to No. 5. The Bulldogs clinched the SEC East crown after defeating No. 11 Kentucky on Saturday, and they will face Alabama in the conference championship game.

The SEC again has a conference-high seven teams in the CFP rankings this week. It is newly represented by No. 24 Auburn after Texas A&M dropped out.
